Children (11) with vitamin D-resistant rickets were treated with a phosphate mixture alone (1.2-3.6 g per day) or combined with ergocalciferol (vitamin D2, 25-50 .times. 103 IU/day) or with calcitriol (1,25-dihydroxyvitamin D3, 0.25 to 1 .mu.g/day). Serum calcitriol concentrations were normal in all patients. Calcitriol therapy raised circulating levels of the hormone to values above normal and increased intestinal phosphate absorption. In some patients this regimen decreased the need for phosphate supplements. No treatment regimen corrected the renal phosphate leak. Radiologic studies and bone histomorphometric analyses showed that phosphate (alone or with ergocalciferol) induced the mineralization of the growth plate but not of the endosteal bone surface. Combined calcitriol and phosphate therapy for 2850 patient-days greatly improved the mineralization of trabecular bone. Short-term episodes of hypercalcemia were easily controlled by changes in calcitriol dosage. The combined calcitriol and phosphate regimen is useful in the treatment of vitamin D-resistant rickets.
